Despite his injuries, Turner began giving first aid and pulled other soldiers to safety. As he worked, he was shot twice — one bullet breaking a bone in his arm. Yet Turner would say later that he felt almost no pain.

"Soldiers in the heat of the moment don't recognize the pain that's happening," Linden says. But once that moment is over, those same soldiers may feel a lot of pain from something minor, like a hypodermic needle, he says.

CIA interrogators used both tactics after Sept. 11, according to a Senate report released late last year.

One system determines the pain's location, intensity and characteristics: stabbing, aching, burning, etc.

there is a completely separate system for the emotional aspect of pain

positive emotions — like feeling calm and safe and connected to others — can minimize pain. But negative emotions tend to have the opposite effect. Torturers have exploited that aspect for centuries.

they want to accentuate pain during torture they can do this with humiliation [or] with an unpredictable schedule of delivering pain

Those things will make the emotional component of the pain experience stronger."

brain also determines the emotion we attach to each painful experience, Linden says. That's possible, he explains, because the brain uses two different systems to process pain information coming from our nerve endings.

One thing scientists are still trying to understand is precisely how the brain regulates the perception of pain

The team studied low-frequency brain waves in a part of the brain that responds to sensations in the hand,

Earlier research had shown that these rhythms increase when the brain is blocking sensory information from the hand.

reseasrchers monitored the brain waves of a dozen people who were asked to pay attention only to their hand or only to their foot. During the experiment the scientists delivered a light tap to each person's finger or toe.

ocused on their feet, low-frequency rhythms increased in the brain area that responds to hand sensations — because participants were asking their brains to ignore sensory input from the hand, and it's these low-frequency rhythms that do the blocking of such information.

low-frequency rhythms also increased in a different brain area — the region that ignores distractions, the team discovered.

The two areas became synchronized

"There's coordination between the front part of the brain, which is the executive control region of the brain, and the sensory part of the brain, which is filtering information from the environment," she says.

suggests that at least some people can teach their brains how to filter out things like chronic pain, perhaps through meditation

It found that people who practiced mindfulness meditation for eight weeks greatly improved their control of the brain rhythms that block out pain.

Eventually Brad Katsuyama came to realize that the most sophisticated investors didn’t know what was going on in their own market. Not the big mutual funds, Fidelity and Vanguard. Not the big money-management firms like T. Rowe Price and Capital Group. Not even the most sophisticated hedge funds.

The deep problem with the system was a kind of moral inertia. So long as it served the narrow self-interests of everyone inside it, no one on the inside would ever seek to change it, no matter how corrupt or sinister it became

If an investor as large as T. Rowe Price, which acted on behalf of millions of investors, had trouble obtaining the information it needed to determine if its brokers had acted in their interest, what chance did the little guy have?

The trouble with the stock market — with all of the public and private exchanges — was that they were fantastically gameable, and had been gamed: first by clever guys in small shops, and then by prop traders who moved inside the big Wall Street banks. That was the problem, Puz thought. From the point of view of the most sophisticated traders, the stock market wasn’t a mechanism for channeling capital to productive enterprise but a puzzle to be solved.

As they worked through the order types, the Puzzle Masters created a taxonomy of predatory behavior in the stock market. Broadly speaking, it appeared as if there were three activities that led to a vast amount of grotesquely unfair trading. The first they called electronic front-running — seeing an investor trying to do something in one place and racing ahead of him to the next (what had happened to Katsuyama when he traded at RBC). The second they called rebate arbitrage — using the new complexity to game the seizing of whatever legal kickbacks, called rebates within the industry, the exchange offered without actually providing the liquidity that the rebate was presumably meant to entice. The third, and probably by far the most widespread, they called slow-market arbitrage. This occurred when a high-frequency trader was able to see the price of a stock change on one exchange and pick off orders sitting on other exchanges before those exchanges were able to react. This happened all day, every day, and very likely generated more billions of dollars a year than the other strategies combined.

IEX had made its point: That to function properly, a financial market didn’t need to be rigged in someone’s favor. It didn’t need payment for order flow and co-location and all sorts of unfair advantages possessed by a small handful of traders. All it needed was for investors to take responsibility for understanding it, and then to seize its controls. “The backbone of the market,” Katsuyama says, “is investors coming together to trade.”

Technology had collided with Wall Street in a peculiar way. It had been used to increase efficiency. But it had also been used to introduce a peculiar sort of market inefficiency. Taking advantage of loopholes in some well-meaning regulation introduced in the mid-2000s, some large amount of what Wall Street had been doing with technology was simply so someone inside the financial markets would know something that the outside world did not. The same system that once gave us subprime-mortgage collateralized debt obligations no investor could possibly truly understand now gave us stock-market trades involving fractions of a penny that occurred at unsafe speeds using order types that no investor could possibly truly understand.

The stock market really was rigged. Katsuyama often wondered how enterprising politicians and plaintiffs’ lawyers and state attorneys general would respond to that realization. (This March, the New York attorney general, Eric Schneiderman, announced a new investigation of the stock exchanges and the dark pools, and their relationships with high-frequency traders.

The purpose of the surgery was to remove electrodes that had previously been implanted in the patients’ brains to monitor seizures. But before they were taken out, the electrodes enabled the researchers to study the activity of individual neurons in the cortex, in addition to large-scale brain activity from EEG recordings.

importance of communication between discrete groups of neurons, both within the cortex and across brain regions, is analogous to a band playing music, said George Mashour, a neuroscientist and anesthesiologist at the University of Michigan, Ann Arbor. “You need musical information to come together either in time or space to really make sense,”

“Consciousness and cognitive activity may be similar. If different areas of the brain aren’t in synch or if a critical area that normally integrates cognitive activity isn’t functioning, you could be rendered unconscious.”

, Purdon and colleagues were able to discern a more detailed neural signature of loss of unconsciousness, this time by using EEG alone. Monitoring brain activity in healthy patients for 2 hours as they underwent propofol-induced anesthesia, they observed that as responsiveness fades, high-frequency brain waves (12–35 hertz) rippling across the cortex and the thalamus were replaced by two different brain waves superimposed on top on one another: a low-frequency (<1 hertz) wave and an alpha frequency (8–12 hertz) wave. “These two waves pretty much come at loss of consciousness,”

“We’ve started to teach our anesthesiologists how to read this signature on the EEG”

Anesthesia is not the only state in which consciousness is lost, of course

o measure the gradual breakdown of connectivity between neural networks during natural REM sleep and anesthesia, as well as in brain-injured, unresponsive patients. Using an electromagnetic coil to activate neurons in a small patch of the human cortex, then recording EEG output to track the propagation of those signals to other neuronal groups, the researchers can measure the connectivity between collections of neurons in the cortex and other brain regions.

minimally conscious patients, the magnetically stimulated signals propagated fairly far and wide, occasionally reaching distant cortical areas, much like activations seen in locked-in but conscious patients. In patients in a persistent vegetative state, on the other hand, propagation was severely limited—a breakdown of connectivity similar to that observed in previous tests of anesthetized patients. What’s more, in three vegetative patients that later recovered consciousness, the test picked up signs of increased connectivity before clinical signs of improvement became evident.

“I think understanding consciousness itself is going to help us find successful [measurement] approaches that are universally applicable,” said Pearce.

Perrow had a fairly simple solution for the problem. High-risk systems, such as nuclear power plants, should be built only as a last resort.

That solution won’t work for financial markets. We need currency hedges, futures markets, and derivatives to keep our economic systems functioning. But we also have to realize tweaking the current system will not fix the problem. Most of the supposedly strong cures implemented by legislators to date, such as prohibiting bank holding companies from proprietary trading, are inadequate as well.

how do we make our markets less danger prone? A good place to start would be to reduce the excessive trading volumes that lie at the root of accidents like the Flash Freeze, Flash Cash, and Goldman debacle. There is no valid reason for high frequency trading to make up more than 50 percent of all stock trades, and there is no pressing need for some $4 trillion in daily foreign currency transactions. A Tobin tax on transactions, first suggested by Noble laureate James Tobin in 1972, of as little as 0.1 percent, would significantly reduce these volumes. Smaller transaction volumes would reduce the size of accidents and possibly their frequency.

But tinkering with the current system and looking for easy ways out, as we are now, is bound to fail. We’re in danger of letting normal accidents in the financial system become all too normal.

For constrained domains the GOFAI approach is a winning strategy.

there is nothing intelligent or even interesting about the brute force approach.

the dominant paradigm in AI research has largely “moved on from GOFAI to embodied, distributed intelligence.” And Faustus from Cincinnati insists that as a result “machines with bodies that experience the world and act on it” will be “able to achieve intelligence.”

The new, embodied paradigm in AI, deriving primarily from the work of roboticist Rodney Brooks, insists that the body is required for intelligence. Indeed, Brooks’s classic 1990 paper, “Elephants Don’t Play Chess,” rejected the very symbolic computation paradigm against which Dreyfus had railed, favoring instead a range of biologically inspired robots that could solve apparently simple, but actually quite complicated, problems like locomotion, grasping, navigation through physical environments and so on. To solve these problems, Brooks discovered that it was actually a disadvantage for the system to represent the status of the environment and respond to it on the basis of pre-programmed rules about what to do, as the traditional GOFAI systems had. Instead, Brooks insisted, “It is better to use the world as its own model.”

although they respond to the physical world rather well, they tend to be oblivious to the global, social moods in which we find ourselves embedded essentially from birth, and in virtue of which things matter to us in the first place.

the embodied AI paradigm is irrelevant to Watson. After all, Watson has no useful bodily interaction with the world at all.

The statistical machine learning strategies that it uses are indeed a big advance over traditional GOFAI techniques. But they still fall far short of what human beings do.

“The illusion is that this computer is doing the same thing that a very good ‘Jeopardy!’ player would do. It’s not. It’s doing something sort of different that looks the same on the surface. And every so often you see the cracks.”

Watson doesn’t understand relevance at all. It only measures statistical frequencies. Because it is relatively common to find mismatches of this sort, Watson learns to weigh them as only mild evidence against the answer. But the human just doesn’t do it that way. The human being sees immediately that the mismatch is irrelevant for the Erie Canal but essential for Toronto. Past frequency is simply no guide to relevance.

The fact is, things are relevant for human beings because at root we are beings for whom things matter. Relevance and mattering are two sides of the same coin. As Haugeland said, “The problem with computers is that they just don’t give a damn.” It is easy to pretend that computers can care about something if we focus on relatively narrow domains — like trivia games or chess — where by definition winning the game is the only thing that could matter, and the computer is programmed to win. But precisely because the criteria for success are so narrowly defined in these cases, they have nothing to do with what human beings are when they are at their best.

Far from being the paradigm of intelligence, therefore, mere matching with no sense of mattering or relevance is barely any kind of intelligence at all. As beings for whom the world already matters, our central human ability is to be able to see what matters when.

But, as we show in our recent book, this is an existential achievement orders of magnitude more amazing and wonderful than any statistical treatment of bare facts could ever be. The greatest danger of Watson’s victory is not that it proves machines could be better versions of us, but that it tempts us to misunderstand ourselves as poorer versions of them.

focus on an ambitious domestic agenda, including the signing of executive orders and legislation to roll back Obama-era regulations.

his time is his most valuable asset.

What’s striking with President Trump is not only how contained his travel has been, but how much of it is around campaign rallies, rather than something he wants to get done

Other researchers reported a consistent association between family dinner frequency and teen academic performance. Adolescents who ate family meals 5 to 7 times a week were twice as likely to get A’s in school as those who ate dinner with their families fewer than two times a week.

Children who eat regular family dinners also consume more fruits, vegetables, vitamins and micronutrients, as well as fewer fried foods and soft drinks.

And the nutritional benefits keep paying dividends even after kids grow up: young adults who ate regular family meals as teens are less likely to be obese and more likely to eat healthily once they live on their own.

Some research has even found a connection between regular family dinners and the reduction of symptoms in medical disorders, such as asthma.

The benefit might be due to two possible byproducts of a shared family meal: lower anxiety and the chance to check in about a child’s medication compliance.

The dinner atmosphere is also important. Parents need to be warm and engaged, rather than controlling and restrictive, to encourage healthy eating in their children.

In a very recent study, kids who had been victims of cyberbullying bounced back more readily if they had regular family dinners.

Family dinners have been found to be a more powerful deterrent against high-risk teen behaviors than church attendance or good grades.

In a New Zealand study, a higher frequency of family meals was strongly associated with positive moods in adolescents. Similarly, other researchers have shown that teens who dine regularly with their families also have a more positive view of the future, compared to their peers who don’t eat with parents.

dinner is the most reliable way for families to connect and find out what’s going on with each other

American teens were asked when they were most likely to talk with their parents: dinner was their top answer

Kids who eat dinner with their parents experience less stress and have a better relationship with them

Of course, the real power of dinners lies in their interpersonal quality. If family members sit in stony silence, if parents yell at each other, or scold their kids, family dinner won’t confer positive benefits.

But, dinner may be the one time of the day when a parent and child can share a positive experience – a well-cooked meal, a joke, or a story – and these small moments can gain momentum to create stronger connections away from the table.

onic constipation, a functional bowel disorder, affects approximately 14% of adults worldwide [1]. Slow transit constipation (STC) is the major cause of chronic constipation which is characterized by markedly prolonged colonic transit time as a result of the colonic motility function disorde

Usually, patients with STC suffer from a common sense of abdominal pain, nausea, depression and sickness, which seriously influence their social ability and health-related quality of life [4–6

Current clinical treatments include cathartics, prokinetics and aggressive surgery which can increase bowel movement frequency to a certain degree.

However, pharmacological interventions is prone to drug dependency and relapse after drug withdrawal [3]

Surgical treatments such as subtotal colectomy and total colectomy in STC patients may adversely affect the quality of life due to the risk of postoperative diarrhea or incontinence, and result in a heavy healthcare burden

The enteric nervous system (ENS), located in the intestinal wall, regulates various functions including contraction of intestine, homeostasis and blood flow [10]. As the ‘second brain’, the ENS contains large amounts of neurons working independently from the central nervous system [11]. Researches have identified that STCs are mostly caused by disorders of the relevant nerves, especially the ENS [12,13].

McCallum et al. [35] found that gastric electrical stimulation in combination with pharmacological treatment could also enhance emptying in patients with gastroparesis. Especially, gastric electrical stimulation has been approved as a clinical therapy method for gastroparesis and obesity in European and American countries [36].

we employed pulse train stimulation and implanted electrodes at the proximal colon in dogs.

After CES treatment, we observed the colonic transit time of the sham treatment group was longer than that of CES treatment and control groups, and electrical stimulation significantly enhanced the colonic electromyogram (EMG) signal.

histopathology and TEM analysis showed increased ganglia and synaptic vesicles existing in the colon myenteric plexus of the CES treatment group as compared with that of the sham CES group

Our results suggested that CES might reduce the degeneration of the myenteric plexus neurons, thereby contributing to the therapeutic effect on STC beagles.

the defecating frequency and the feces characteristics of STC beagles returned to normal after CES treatment. The result indicated that CES could improve the symptoms of STC.

The colonic EMG signal was strongly promoted by CES

Especially, the colonic EMG signal of the beagles with STC was remarkably enhanced by CES (Figure 3), indicating that CES could not only improve the colonic content emptying, but also enhance the EMG signal to promote colonic motility.

Colonic electrical stimulation (CES), a valuable alternative for the treatment of STC, was reported to improve the colon motility by adjusting the bioelectrical activity in animal models or patients with STC [17]. However, little report focuses on the underlying nervous mechanism to normalize the delayed colonic emptying and relieve symptoms. We hypothesized that CES may also repair the disorders of the relevant nerves and then improve the colonic motility.

The first study regarding the CES to modulate colonic motility was performed by Hughes et al. [37]. Since then, many researchers employed short-pulse CES in canine descending colon or pig cecum [20,21,38]. Researchers also applied long-pulse CES to stimulate the colon of human or animals [39]

Recently, studies showed that the prokinetic effect of pulse train CES is better than that of short-pulse CES or long-pulse CES [25]

Our study indicated that CES could enhance the colonic motility, and then accelerate the colonic content emptying. Thereafter, we investigated the underlying mechanism and presumed that CES might improve the STC symptom through the repairment of the ENS.

The neuropathy in ENS is considered to be responsible for various kinds of disordered motility including STC and the related pathophysiologic symptoms [40]. In agreement with this view, our study discovered the decreased number of ganglia in the myenteric plexus, as well as the destruction of the enteric nerve axon terminals and synaptic vesicles in the sham CES group beagles

The present study proves that CES with pulse trains has curative effects on the colonic motility and content emptying in STC beagles. The up-regulation of intestinal nerve related proteins such as SYP, PGP9.5, CAD and S-100B in the colonic myenteric plexus suggests that CES might reduce the degeneration of the myenteric plexus neurons, thereby producing the therapeutic effect on STC beagles. Further investigation for the underlying mechanism of nerve regeneration is necessary to better understand how CES promotes the recovery of delayed colonic motility induced by STC.

the "you choose who to let in" narrative is powerful because it trades on traditional notions of space and boundary regulation, and further appeals to our heightened sense of individual responsibility, and, possibly even vanity. The basic message is that so long as we exercise good judgment when selecting our friends, no privacy problems will arise

What this appeal to status quo relations and existing privacy settings conceals is the transformative potential of Graph : new types of searching can emerge that, due to enhanced frequency and newly created associations between data points, weaken, and possibly obliterate obscurity.

the stalker frame muddies the concept, implying that the problem is people with bad intentions getting our information. Determined stalkers certainly pose a threat to the obscurity of information because they represent an increased likelihood that obscure information will be found and understood.

he other dominant narrative emerging is that the Graph will simplify "stalking."

Well-intentioned searches can be problematic, too.

It is not a stretch to assume Graph could enable searching through the content of posts a user has liked or commented on and generating categories of interests from it. For example, users could search which of their friends are interested in politics, or, perhaps, specifically, in left-wing politics.

In this scenario, a user who wasn't a fan of political groups or causes, didn't list political groups or causes as interests, and didn't post political stories, could still be identified as political.

In a system that purportedly relies upon user control, it is still unclear how and if users will be able to detect when their personal information is no longer obscure. How will they be able to anticipate the numerous different queries that might expose previously obscure information? Will users even be aware of all the composite results including their information?

Obscurity is a protective state that can further a number of goals, such as autonomy, self-fulfillment, socialization, and relative freedom from the abuse of power. A major task ahead is for society to determine how much obscurity citizens need to thrive.

Facebook, for all the unprecedented connection it fosters among previously atomized people, fosters a very particular kind of connection: one that is mediated, at all times, by Facebook. And one that therefore makes very particular kinds of assumptions about how and why people connect in the first place. Facebook "connection" is defined -- semantically, at least -- by friendship. ("Facebook friends," "friending people," etc.) While it doesn't assume that every connection is an actual friend, in the narrow and maybe even old-fashioned sense of the word, Facebook's infrastructure does assume esteem among people who friend each other.

The study itself, in fact, is confirming the hypothesis that Rauch and Schanz started with: "We predict," they noted, "that due to potential chronic traits and/or their adaptation to a Facebook culture of shallow processing and agreement, frequent Facebook users are highly susceptible to persuasive messages compared to less frequent users.

This is, to say the least, troubling.

Facebook, as a result, is structured as an aggressively upbeat place.

social complicity. You can argue on Facebook, but it is not really encouraged. And the interactions Facebook fosters as it expands -- the status updates, the information sharing, the news consumption -- stem from that default-positive place. "Like," but not "Dislike." "Recommend," but not "Reject."

That's significant, because Facebook wants to expand from social connection into informational connection. The News Feed as the "personalized newspaper"; the just-introduced Home as a mobile locus of that newspaper.

Heavy users of Facebook tend to use the site because of a desire for social inclusion. In that context, the study suggests, those users are primed to agree with fellow users rather than to criticize the information those users share. And not just in terms of their public interactions, but in terms of their private beliefs. This potent combination -- "a need to connect and an ethos of shallow processing" -- provides a warm, moist breeding ground for the spread of opinions, publicly and not-so-publicly. Racist ones among them.

What will happen if information gets fully social -- according to Facebook's definition of "fully social"? What will take place when the Jack Browns of the world aren't just our friends, but our news sources?

That’s why we think of scent as a trigger for personal memory — leading to the recall of something specific, particular, uniquely our own.

When the research team visited the Jahai, rain-forest foragers on the Malay Peninsula, they found that the Jahai were succinct and more accurate with the scratch-and-sniff cards.

The team also found that several communities — speakers of Persian, Turkish and Zapotec — used different metaphors than English and Dutch speakers to describe pitch, or frequency: Sounds were thin or thick rather than high or low. In later work, they demonstrated that the metaphors were powerful enough to disrupt perception.

younger Cantonese speakers had fewer words for tastes and smells than older ones, a shift attributed to rapid socioeconomic development and Western-style schooling.

“Why do we have music?” Dr. Kanwisher said in an interview. “Why do we enjoy it so much and want to dance when we hear it? How early in development can we see this sensitivity to music, and is it tunable with experience? These are the really cool first-order questions we can begin to address.”

Dr. McDermott said the new method could be used to computationally dissect any scans from a functional magnetic resonance imaging device, or F.M.R.I. — the trendy workhorse of contemporary neuroscience — and so may end up divulging other hidden gems of cortical specialization. As proof of principle, the researchers showed that their analytical protocol had detected a second neural pathway in the brain for which scientists already had evidence — this one tuned to the sounds of human speech.

Importantly, the M.I.T. team demonstrated that the speech and music circuits are in different parts of the brain’s sprawling auditory cortex, where all sound signals are interpreted, and that each is largely deaf to the other’s sonic cues, although there is some overlap when it comes to responding to songs with lyrics.

In fact, Dr. Rauschecker said, music sensitivity may be more fundamental to the human brain than is speech perception. “There are theories that music is older than speech or language,” he said. “Some even argue that speech evolved from music.”

, many researchers had long assumed that the human brain must be equipped with some sort of music room, a distinctive piece of cortical architecture dedicated to detecting and interpreting the dulcet signals of song. Yet for years, scientists failed to find any clear evidence of a music-specific domain through conventional brain-scanning technology

when previous neuroscientists failed to find any anatomically distinct music center in the brain, they came up with any number of rationales to explain the results.“The story was, oh, what’s special about music perception is how it recruits areas from all over the brain, how it draws on the motor system, speech circuitry, social understanding, and brings it all together,” she said. Some researchers dismissed music as “auditory cheesecake,” a pastime that co-opted other essential communicative urges. “This paper says, no, when you peer below the cruder level seen with some methodologies, you find very specific circuitry that responds to music over speech.”

The researchers wondered if the auditory system might be similarly organized to make sense of the soundscape through a categorical screen. If so, what would the salient categories be? What are the aural equivalents of a human face or a human leg — sounds or sound elements so essential the brain assigns a bit of gray matter to the task of detecting them?

Focusing on the brain’s auditory region — located, appropriately enough, in the temporal lobes right above the ears — the scientists analyzed voxels, or three-dimensional pixels, of the images mathematically to detect similar patterns of neuronal excitement or quietude.“The strength of our method is that it’s hypothesis-neutral,” Dr. McDermott said. “We just present a bunch of sounds and let the data do the talking.”

Matching sound clips to activation patterns, the researchers determined that four of the patterns were linked to general physical properties of sound, like pitch and frequency. The fifth traced the brain’s perception of speech, and for the sixth the data turned operatic, disclosing a neuronal hot spot in the major crevice, or sulcus, of the auditory cortex that attended to every music clip the researchers had played.

“The sound of a solo drummer, whistling, pop songs, rap, almost everything that has a musical quality to it, melodic or rhythmic, would activate it,” Dr. Norman-Haignere said. “That’s one reason the result surprised us. The signals of speech are so much more homogeneous.”

The researchers have yet to determine exactly which acoustic features of music stimulate its dedicated pathway. The relative constancy of a musical note’s pitch? Its harmonic overlays? Even saying what music is can be tricky.

last year Mr. Santorum made a point of defending the medieval Crusades against the “American left who hates Christendom.” Historical issues aside (hey, what are a few massacres of infidels and Jews among friends?), what was this doing in a 21st-century campaign?

Nor is this only about sex and religion: he has also declared that climate change is a hoax, part of a “beautifully concocted scheme” on the part of “the left” to provide “an excuse for more government control of your life.” You may say that such conspiracy-theorizing is hardly unique to Mr. Santorum, but that’s the point: tinfoil hats have become a common, if not mandatory, G.O.P. fashion accessory.

Then there’s Ron Paul, who came in a strong second in Maine’s caucuses despite widespread publicity over such matters as the racist (and conspiracy-minded) newsletters published under his name in the 1990s and his declarations that both the Civil War and the Civil Rights Act were mistakes. Clearly, a large segment of his party’s base is comfortable with views one might have thought were on the extreme fringe.

Finally, there’s Mr. Romney, who will probably get the nomination despite his evident failure to make an emotional connection with, well, anyone. The truth, of course, is that he was not a “severely conservative” governor. His signature achievement was a health reform identical in all important respects to the national reform signed into law by President Obama four years later. And in a rational political world, his campaign would be centered on that achievement.

The social medium of choice for the self-absorbed appears to be Twitter. The researchers found an association between tweeting about oneself and high narcissism scores.

“We think we’re all unique, and we think every novel is individual, and it is. So when they reduce us all to a bunch of data about words, I guess you have to laugh.

A 1999 study found that when social and economic conditions were bad, movie actresses with “mature facial features” — small eyes, thin cheeks, large chins — were popular, but when conditions were good, the public liked actresses with childlike features.

In the new study, researchers also analyzed 650,000 German books and found the same misery correlation.

Still, the practice of applying data-sorting algorithms to art can only go so far. For one thing, the lists of emotion words, created by other researchers and used for years, include some surprising choices: words like “smug” and “wallow” were among 224 words on the “joy” list; potentially neutral adjectives like “dark” and “low” were among 115 words on the “sadness” list.

People in their 20s experienced a 26 percent drop in performance when they were asked to try to drive and identify signs at the same time (rather than just identify the signs without driving). For people in their 60s to 80s, the performance drop was 64 percent.

But after the older adults trained at the game, they became more proficient than untrained people in their 20s. The performance levels were sustained for six months, even without additional training. Also, the older adults performed better at memory and attention tests outside the game.

The researchers created a second layer of proof by monitoring the brain waves of participants using electroencephalography. What they found was that in older participants, in their 60s to 80s, there were increases in a brain wave called theta, a low-level frequency associated with attention.

Creativity moves beyond mere synthesis and evaluation and is, he says, “the higher order skill.” This has not been a sudden development. Nearly 20 years ago “creating” replaced “evaluation” at the top of Bloom’s Taxonomy of learning objectives. In 2010 “creativity” was the factor most crucial for success found in an I.B.M. survey of 1,500 chief executives in 33 industries. These days “creative” is the most used buzzword in LinkedIn profiles two years running.

The method, which is used in Buffalo State classrooms, has four steps: clarifying, ideating, developing and implementing. People tend to gravitate to particular steps, suggesting their primary thinking style.

What’s igniting campuses, though, is the conviction that everyone is creative, and can learn to be more so.

Just about every pedagogical toolbox taps similar strategies, employing divergent thinking (generating multiple ideas) and convergent thinking (finding what works).The real genius, of course, is in the how.

as content knowledge evolves at lightning speed, educators are talking more and more about “process skills,” strategies to reframe challenges and extrapolate and transform information, and to accept and deal with ambiguity.

Clarifying — asking the right question — is critical because people often misstate or misperceive a problem. “If you don’t have the right frame for the situation, it’s difficult to come up with a breakthrough,

Ideating is brainstorming and calls for getting rid of your inner naysayer to let your imagination fly.

Developing is building out a solution, and maybe finding that it doesn’t work and having to start over

Implementing calls for convincing others that your idea has value.

“the frequency and intensity of failures is an implicit principle of the course. Getting into a creative mind-set involves a lot of trial and error.”

His favorite assignments? Construct a résumé based on things that didn’t work out and find the meaning and influence these have had on your choices.

“Examine what in the culture is preventing you from creating something new or different. And what is it like to look like a fool because a lot of things won’t work out and you will look foolish? So how do you handle that?”

Because academics run from failure, Mr. Keywell says, universities are “way too often shapers of formulaic minds,” and encourage students to repeat and internalize fail-safe ideas.

“The new people who will be creative will sit at the juxtaposition of two or more fields,” she says. When ideas from different fields collide, Dr. Cramond says, fresh ones are generated.

Basic creativity tools used at the Torrance Center include thinking by analogy, looking for and making patterns, playing, literally, to encourage ideas, and learning to abstract problems to their essence.

students explore definitions of creativity, characteristics of creative people and strategies to enhance their own creativity.These include rephrasing problems as questions, learning not to instinctively shoot down a new idea (first find three positives), and categorizing problems as needing a solution that requires either action, planning or invention.

The United States has one of the world’s largest pay gaps, with chief executives earning nearly 300 times what the average worker makes, according to some economists’ estimates. That is much higher than the 20-to-1 ratio recommended by Gilded Age magnates like J. Pierpont Morgan and the 20th century management visionary Peter Drucker.

“The market rate for me as a C.E.O. compared to a regular person is ridiculous, it’s absurd,” said Mr. Price, who said his main extravagances were snowboarding and picking up the bar bill. He drives a 12-year-old Audi

Under a financial overhaul passed by Congress in 2010, the Securities and Exchange Commission was supposed to require all publicly held companies to disclose the ratio of C.E.O. pay to the median pay of all other employees, but it has so far failed to put it in effect. Corporate executives have vigorously opposed the idea, complaining it would be cumbersome and costly to implement.

Of all the social issues that he felt he was in a position to do something about as a business leader, “that one seemed like a more worthy issue to go after.”

The happiness research behind Mr. Price’s announcement on Monday came from Angus Deaton and Daniel Kahneman, a Nobel Prize-winning psychologist. They found that what they called emotional well-being — defined as “the emotional quality of an individual’s everyday experience, the frequency and intensity of experiences of joy, stress, sadness, anger, and affection that make one’s life pleasant or unpleasant” — rises with income, but only to a point. And that point turns out to be about $75,000 a year.

Of course, money above that level brings pleasures — there’s no denying the delights of a Caribbean cruise or a pair of diamond earrings — but no further gains on the emotional well-being scale.

As Mr. Kahneman has explained it, income above the threshold doesn’t buy happiness, but a lack of money can deprive you of it.
